Ginza Yamaji is one of the best places in Ginza to get a high-end kaiseki course meal. If you've got the money to spend, you won't regret choosing Yamaji for a fancy dinner night in Ginza.
'Yoshizawa' (よし澤) in Roppongi Hills is the second location of a well-known Ginza kaiseki restaurant that has a Michelin Star. The food here is just as good, but it's much easier to get a reservation since the Roppongi location doesn't have a Michelin Star... Yet. If you're searching for an awesome kaiseki meal in Tokyo, Yoshizawa is a great option!
